If you’ve got the same rotten luck as me, you might find that the Windows 7 beta doesn’t work very nicely with virutal ISO mounting programs yet. I’m not the type to pay for software, and so most free options seem to only make Win7 hang if you try to open My Computer, or do a commandline “cd” into the virtual drive.

But I just tried MS’s UNofficial tool for windows xp to mount iso files, and it works great. It’s not quite as “nice” to you as other programs out there, but if it’s the only thing that works, then why not use it? 🙂
